Abstract

.

The FBI tracks active shooting cases—where individuals attempt to kill people in public places, excluding those tied to robberies or gang violence. This study is the first to systematically compare how uniformed police and civilians with concealed handgun permits perform in stopping these attacks. Civilians with permits stopped the attacks more frequently and faced a lower risk of being killed or injured than police. Officers who intervened during the attacks were far more likely to be killed or injured than those who apprehended the attackers later. We also provide evidence that these numbers significantly underestimate the advantages of civilians over officers in stopping these attacks. We explore the implications of two possible identification problems. There is some evidence that passage of Constitutional Carry laws reduce the number of active shooting attacks.

    Keep them coming, please.
